Solved Compatibily of c++ v.3.0 with 64-bit processor

January 27, 2013 at 11:18:50
Specs: Windows 7

I have constructed a number of programs using c++ and C++ compiler on my 32-bit Dell PC. None of these programs will run on my new 64-bit computer from HP. How can I salvage my work? Can programs be translated(?), can a new compatible compiler be purchased or downloaded? Just what can be done.
Your comment &advice will be appreciated.

First of all the warning message issued by MS Virtual PC is for Microsoft maintenance policies only and I am sure it can be ignored with no consequences. I guided to the same installation a college student running Windows 7 Home Premium 64 bit. So I am surprised you faced troubles forcing the installation process to go ahead. If you wish, contact me by a private message with your e-mail address and I will send you the instructions I wrote for that student.

Another virtual machine you can install without any restriction is the open source VirtualBox (obviously free). VirtualBox is even better than MS Virtual PC but lacks sharing facilities for DOS guest environment that can be connected to the host OS only via virtual LAN or using disk images.

You can download Visual C++ Express from Microsoft at no cost. You will probably need to make some adustments to your programs to get them to compile and run as you have been using a very old 16-bit compiler.

The way pointed out by ijack is the king road, another solution is to install a virtual machine, run DOS as guest operating system inside and transfer your 16 bit programs to the virtual environment without any manipulation.

As virtual machine I suggest MS Virtual PC from Microsoft (free) and as DOS the free open source FreeDOS, 99% compatable with the original MS DOS.

If eventually you choose this way, I can send you two modules to share the files/folders between host and guest environments so simplifying applications management.

Thanks to both of (ijack and ivo). I will try to get the MS virtual PC and see what happens. Incidentally, pardon my misspelling of "Compatibility"!

Well, I am not out of the woods, yet! I have tried to install the Microsoft Virtual PC but was promptly informed that my Windows 7Home Premium would not support it. I tried to run anyway but got nowhere and I uninstalled it. So, here I am at square one, again. I searched for a version of the download that would work but I found no reference to my Windows OS. Incidentally, my processor is AMD64. Fortunately, I still have old 32-bit computer but I am searching for ways to move my work to HP Pavilion. Any suggestions ?

Thank you, again. I will repeat the installation.
